Letters Patent No. 111,588, dated February l', 1871.

IMPRQVEMENT IN FLUTING-MACHINES.

The Schedule referred to in these Letters Patent and making p art of the same.

I, THEoDoRE M. TUCKER, oi thevcty of Newark, in the county of Essex and State of New Jersey, have invented certain Improvements in Fluting-Macliines, 'of which the following is a specification.

Tl1e.fi1'st part of' my improvement relates to' the means employed for separation of the rollers and the admit the combined rack and guide E, the guide being an integral part of the movable frame B.

The slide-guide E is a frame with a rack on the inner side of one of the uprights.

Provision is made on the top bar of the main frame I. for bearings for a pinion, y, to be operated by the lever-handle W. v v

vBy means of the rack z and pinion y the upper roller D is lifted for the insertion of the material to be iluted between the rollers.

To hold and guide spiral springs of the required strength and tension without incumbrance to the frame, two projections, 'grand c, are cast-upon the main frame, with holes from below through the bar to receive the spiral springs, as 'shown by the dotted lines, the tension of the springs s and t being graduated by the thumb-screws p and rthat are tapped through the solid tops of the projections u and fv.

I claim as my improvement- 'lhe rack z and pinion y, the projections 'u Iand u, spiral springs s andt,1;be movable frame B and its roller D, constructed, combined, and arranged as and for the purpose shown and described.
